ZIPArchive

A 4D ZIP archive is a File or Folder object containing one or more files or folders, which are compressed to be smaller than their original size. These archives are created with a ".zip" extension and can be used to save disk space or transfer files via mediums which may have size limitations (e.g., email or network).

• You create a 4D ZIP archive with the ZIP Create archive command.
• 4D ZIPFile and ZIPFolder instances are available through the root property (ZIPFolder) of the object returned by ZIP Read archive command.

Example

To retrieve and view the contents of a ZIP file object:

var $path; $archive : 4D.File
var $zipFile : 4D.ZipFile
var $zipFolder : 4D.ZipFolder
var $txt : Text

$path:=Folder(fk desktop folder).file("MyDocs/Archive.zip")
$archive:=ZIP Read archive($path)
$zipFolder:=$archive.root // store the zip main folder
$zipFile:=$zipFolder.files()[0] //read the first zipped file

If($zipFile.extension=".txt")
